DaffodilThis month we really feel that Spring has arrived.  Most bulbs planted in the fall bloom this month.  Lawns are green and lush.  All my listed lawn tasks are for bluegrass or tall fescue.

  • Aerate your lawn this month
  • Apply a pre-emergent herbicide to lawn if you’ve had a crabgrass problem no later than late-April
  • If using a ‘Feed and Weed’ fertilizer on your lawn to prevent crabgrass or other sprouting weeds, don’t seed your lawn now as grass seed will not sprout – wait until fall to over-seed, which is the preferred season
  • After bulb plants (tulips, daffodils, iris reticulata) bloom, leave the foliage until it turns yellow to allow the plant to store food for next years spring display
  • Perennials start to grow, so cut back any remaining brown stems from last season
  • Divide fall-blooming perennial plants late this month
  • Cut back ornamental grasses at the base and apply fertilizer at 1 pound per 100 square feet (throw a handful on the soil adjacent to the outside perimeter)
  • Plant hardy annual seed outside; calendula, larkspur, pansy and snapdragon
  • Remove tree wrap
  • Fertilize deciduous trees and shrubs (less is better during drought to avoid lush growth that needs more water)
  • Continue to transplant or plant bare-root roses by mid-April
  • Start to remove mounding from rose bushes in late April
  • Prune and fertilize hybrid tea roses the last week of April.  Climbing and shrub roses should have only dead wood removed.
